Is the global command only for DBPro? I've seen it on the forums, but whenever I use it in DBC, the compiler doesn't recognize it.

If that's the case, is it possible to declare global variables in DBC without using arrays?

Someone has to know about this. Doesn't anyone use global variables?

Just initialize the variable at the top of your program (outside a function) and it should be global.

Variable=0

no need for the Global keyword.

Lmao this isn't C++, you can't do that. Globals don't exist in DBC.

To all,

Global does exist in DBC, but only as an array.
For example:
DIM variable(1,2)
variable(1,1) = 1
variable(1,2) = 1

In decalring a variable this way, at the top of your program and outside a function, you have created a global variable, able to be used inside and outside functions and throughout your program, even in #INCLUDE files.

Nano got it right. Whenever I need a global variable in DBC I just declare an array with an index of zero:

DIM MyGlobal(0)

I think mathkid knew that option. That would explain his sentence:
"If that's the case, is it possible to declare global variables in DBC without using arrays?"

But apart from the array work-around, there's no way of declaring global variables in DBC.

Thanks everyone. hyrichter, your tip is a really good idea. I was trying to find a way to make global variables without using huge arrays ( like player position = somearray(37) ) and I think that will work just fine.
